questions about Progesterone labs

I went to two gynecologists, as I wanted a second opinion about my progesterone levels. But I feel dissatisfied and confused with the second doctors response based on the blood work. My progesterone was nearly 1 at day 21 blood draw. That doctors suggested I have low progesterone and would need to do hormone replacement to conceive or to Naturally Supplament to increase my levels. Well, not everyone is a 28 day cycle. I went to hormone specialist as I was weary of accurate results. My progesterone based on temperature cycle, day 23 blood was drawn, 7days past ovulation and my progesterone is at 5. This doctor says I'm ovulating and that's it. Isn't 7days past ovulation the levels supposed to be double or triple. Is this something I should get a third opinion on or go back to the first doctor. I feel even more confused why Dr 2 would think this level is appropriate. Any advise would be insightful. My fiancé and I have concerns about being able to conceive and not sure if it's fine like the dr said for the second opinion or if I should go back to dr 1.
